A novel method for assaying major metabolites of 6 kinds of polycyclic aromatic hydrocarbons in human urine by RP-HPLC-UV were established. These were detected at 280 nm and separated on Dia-monsil TM C18(5 μm,150 nm × 4. 6 nm)by using sodium acetate buffer solution(66: 34,V: V)as mobile phase when the flow rate was 0. 95 mL/ min. The result showed that the calibration curves of 9-hydroxy-phenanthrene,α-naphthol,β-naphthol,1-hydroxypyrene,2-hydroxyfluorene and 9-hydroxyfluorene showed good linearities in the ranges of 0. 105 ~ 500. 0 μmol/ L,0. 106 ~ 135. 0 μmol/ L,0. 120 ~135. 0 μmol/ L,0. 085 ~ 50. 0 μmol/ L,0. 094 ~ 200. 0 μmol/ L and 0. 101 ~ 200. 0 μmol/ L,respective-ly. The relative standard deviations(RSD)were 2. 5% ~ 4. 4% ,2. 1% ~ 4. 3% ,2. 3% ~ 3. 2% ,1. 7% ~3. 9% ,1. 9% ~ 2. 6% ,1. 8% ~ 3. 5%( n = 6)and the average recoveries were 92. 6% ,100. 4% , 101. 0% ,91. 0% ,106. 7% and 95. 5% ,respectively. The proposed method was accurate and suitable for the identification and quantification of these compositions in human urine.
